You're right, and IIRC this symbol has been proposed before unsuccessfully. But recent events have called to attention the backstory behind Prince's symbol---how it was created for use as a tool to modify an unfair contract, and how that successful hack opened up the recording industry for artists---many articles were printed about it at the time (most of them missing the point), a few books were written since, lots more articles were published about it last week, and likely more books about Prince are being written now. A code point is needed for Prince's symbol now. It's no longer merely pop culture but history and law.
